Abstract (en)
This application provides a charge method and charge apparatus for battery, able to effectively charge the battery in low-temperature environments. The charge method includes: obtaining temperature of a battery; when the temperature of the battery is lower than a preset temperature threshold, determining to use a first charge current to charge the battery until the battery meets a preset condition, and then determining to use a second charge current to charge the battery, where the first charge current is used for heating the battery during charging, and the first charge current is greater than the second charge current.
